1x and 1xEV-DO hybrid call setup

Abstract

Systems and methods for hybrid call setup in a wireless communication system are disclosed. A page is sent on a first network informing a target device of a pending communication on a second network. The page also informs the target device a short data burst (SDB) will be sent on the first network. The short data burst (SDB) is sent on the first network containing setup information regarding the pending communication on the second network.

What is claimed is: 
     
       1. A method for wireless communications comprising:
 sending a page on a first network to a target, wherein the page includes information indicative of a pending communication on a second network and an indication that additional information will be sent to the target on the first network; 
 receiving, on the first network, as a response, acknowledgment of receipt of the page from the target; and 
 sending the additional information on the first network, wherein the additional information comprises setup information regarding the pending communication on the second network. 
 
     
     
       2. The method of  claim 1 , wherein the additional information is sent as a short data burst (SDB). 
     
     
       3. The method of  claim 1 , wherein the page is sent by a wireless infrastructure in communication with the target. 
     
     
       4. The method of  claim 1 , wherein the page is generated in response to a connection request from an originator. 
     
     
       5. The method of  claim 4 , wherein the originator is at least one of an access terminal, a remote server, a group communication server, an application server, and a media server. 
     
     
       6. The method of  claim 1 , further comprising:
 maintaining a connection between the first network and the target for transmittal of the additional information. 
 
     
     
       7. The method of  claim 6 , wherein the target:
 receives the additional information; 
 acknowledges the additional information; and 
 accesses the second network using the additional information to receive the pending communication. 
 
     
     
       8. The method of  claim 7 , further comprising:
 receiving the additional information acknowledgement on the first network; and 
 communicating with the target on the second network. 
 
     
     
       9. The method of  claim 8 , further comprising:
 opening a traffic channel on the second network for communication between an originator and the target. 
 
     
     
       10. The method of  claim 1 , further comprising:
 generating a push-to-talk (PTT) signal at an originator; and 
 sending a connection request to a group communication server, wherein the group communication server communicates with the first network to send the page. 
 
     
     
       11. The method of  claim 10 , wherein the connection request is sent on the second network. 
     
     
       12. The method of  claim 10 , further comprising:
 establishing a traffic channel with the second network with the originator. 
 
     
     
       13. The method of  claim 10 , wherein the originator is at least one of an access terminal, a wireless client device, a wireline device, a personal digital assistant (PDA), and a mobile terminal. 
     
     
       14. The method of  claim 1 , wherein the first network has a faster paging interval than the second network and wherein the second network has higher bandwidth than the first network. 
     
     
       15. The method of  claim 14 , wherein the first network is a 1x-RTT network and the second network is a 1x EV-DO network. 
     
     
       16. A non-transitory computer readable media embodying a method for hybrid call setup in a wireless communication system, the method comprising:
 sending a page on a first network to a target, wherein the page includes information indicative of a pending communication on a second network and an indication that additional information will be sent to the target on the first network; 
 receiving from the target, on the first network, as a response to the page, an acknowledgment of receipt of the page; and 
 sending the additional information on the first network, wherein the additional information comprises setup information regarding the pending communication on the second network. 
 
     
     
       17. The non-transitory computer readable media of  claim 16 , wherein the method further comprises:
 receiving the acknowledgement on the first network; and 
 communicating with the target on the second network. 
 
     
     
       18. The non-transitory computer readable media of  claim 16 , wherein the method further comprises:
 opening a traffic channel on the second network for communication between an originator and the target. 
 
     
     
       19. A communication apparatus comprising:
 means for sending a page on a first network to a target, wherein the page includes information indicative of a pending communication on a second network and an indication that additional information will be sent to the target on the first network; 
 means for receiving from the target, on the first network, as a response to the page, an acknowledgement of receipt of the page; and 
 means for sending the additional information on the first network, wherein the additional information comprises setup information regarding the pending communication on the second network. 
 
     
     
       20. The communication apparatus of  claim 19 , further comprising:
 means for generating a push-to-talk (PTT) signal at an originator; and 
 means for sending a connection request to a group communication server from the originator, wherein the group communication server communicates with the first network to send the page. 
 
     
     
       21. The communication apparatus of  claim 19 , wherein the target comprises:
 means for receiving the additional information at the target; 
 means for acknowledging the additional information; and 
 means for accessing the second network using the additional information to receive the pending communication. 
 
     
     
       22. The communication apparatus of  claim 21 , further comprising:
 means for receiving the additional information acknowledgement on the first network; and 
 means for communicating with the target on the second network. 
 
     
     
       23. An apparatus for hybrid call setup in a wireless communication system comprising:
 logic configured to send a page on a first network to a target, wherein the page includes information indicative of a pending communication on a second network and an indication that additional information will be sent to the target on the first network; 
 logic configured to receive, on the first network, as a response, acknowledgment of receipt of the page from the target; and 
 logic configured to send the additional information on the first network, wherein the additional information comprises setup information regarding the pending communication on the second network.
